Collections

Collections are typed sets of objects. Sync or load data into them. Query across them with live queries and write locally to them using optimistic mutations.

Live Queries

Live queries run reactively against and across collections. They're super fast, powered by differential dataflow, with support for joins, filters and aggregates.

Optimistic mutations

Batch and stage instant local changes across collections. Sync transactions to the backend with automatic management of rollbacks and optimistic state.

Blazing fast apps

Built on a Typescript implementation of differential dataflow, TanStack DB gives you real-time sync, live queries and local writes. With no stale data, super fast re-rendering and sub-millisecond cross-collection queries, even for large complex apps.
